....we must review the relevant literature and describe our experimental apparatus. 19 Related Work The combination of document retrieval results has received considerable attention in the past few years: it has been the subject of several doctoral dissertations [4, 53, 74, 67] journal articles [70, 26, 76], and conference papers [23, 7, 42, 35, 43, 54, 75] being especially used by systems competing in the TREC competitions [25, 68, 56] This chapter reviews the results of previous studies as they relate to our work. 2.1 Preliminaries Before we begin looking at speci c metasearch techniques we ....
....[49] corroborate Lee s ndings that CombMNZ improves performance when the systems being combined return di erent irrelevant documents. Ng et al. 56] nd that no improvement is gained when fusing two very di erent routing task algorithms by averaging their normalized relevance scores. Fox et al. [26] use a fusion formula that incorporates the maximum score a document receives, the minimum score, the average score, and the number of systems that retrieves it. Hull et al. 35] try metasearch via averaging on the document ltering problem. The four systems they fuse each outputs an estimate for ....

....relationship information. Traditionally, map outputs have been paper based and only resolve structure at a few discrete levels. However, in recent years, several systems have been reported that use a computer display and allow some navigation of the map space. 2. 3 Visualization tools SENTINEL [5] is a Harris Corporation package that combines a retrieval engine using n grams and context vectors for effective query with a visualization system called VisualEyes . The visualization tool allows the user to interact with document clusters in a three dimensional space. Chen [3] uses a VRML 2.0 ....

....Traditionally, map outputs have been paper based and only resolve structure at a few discrete levels. However, in recent years, several systems have been reported that use a computer display and allow some navigation, browsing, and filtering of the map space. 2. 2 Visualization tools SENTINEL [12] is a Harris Corporation package that combines a retrieval engine using n grams and context vectors for effective query with the VisualEyes visualization system. The visualization tool allows the user to interact with document clusters in a threedimensional space. Chen [9,13] uses a VRML 2.0 ....

....retrieval effectiveness over the individual engines and previous methods. FIRE improves on these results. Finally, an information retrieval system, called SENTINEL, that supports both the fusion of multiple engines and a three dimensional, interactive, visualization user interface is described in [Fox98]. Accuracy assessments using TREC 6 data are presented, but not for the individual engines that are fused. Since the underlying search engines used are proprietary and their individual scores are not presented, it is not possible to independently evaluate the actual fusion algorithm. Other fusion ....
